Radiative‑cooling thermoelectric devices (RCTDs) exploit the temperature gradient between a surface that passively emits infrared radiation to deep space and an underlying thermoelectric (TE) module to generate electricity without external fuel. Here we present , the latest generation of this technology, featuring a multilayer metasurface that achieves a net radiative‑cooling power of 105 W m⁻² under clear‑sky conditions, coupled to a high‑performance Bi₂Te₃‑based TE leg array optimized for low‑temperature operation. Laboratory and field tests demonstrate a peak power density of 6.2 mW cm⁻² , a conversion efficiency of 3.1 % , and continuous operation for more than 10,000 h with less than 1 % performance degradation. RCTD‑031 represents a viable route toward off‑grid power generation for Internet‑of‑Things (IoT) sensors, remote environmental monitoring stations, and low‑power communication relays.
is the result of a five‑year collaborative effort aimed at overcoming the three critical barriers: (i) maximizing net radiative cooling power under realistic sky conditions, (ii) engineering TE legs that maintain high ZT in the low‑ΔT regime, and (iii) integrating the system in a robust, manufacturable package.
If the concept of RCTD-031 appeals to you, there are other similar films worth exploring. The studio ROCKET has produced other RCTD films with comparable themes. For example, is another film in the series with a runtime of 120 minutes and a similar 'family game' premise. Another notable film is RCTD-404 , which also involves a "stop time" family fantasy, indicating ROCKET's strong commitment to high-concept, niche narratives. For those interested in the actresses, Mary Tachibana and Riri Kōda have extensive individual filmographies that can be explored further.
